How it works

Tax year: 2025. These are the latest full return figures Delaware has published.

Delaware taxes income at 2.2% to 6.6%. Enter income before state deductions and choose whether to apply the state standard deduction and personal exemptions, or enter taxable income and switch them off. The tool computes state income tax only; credits other than those named are not applied.

Delaware uses one rate table for every filing status: nothing on the first $2,000, then 2.2 to 5.55 percent, and 6.6 percent over $60,000. The table is the one effective January 1, 2025 in the Division of Revenue employer guide. The standard deduction is $3,250 ($6,500 on a joint return) and each personal exemption is a $110 credit.

Local taxes: Wilmington levies a 1.25 percent earned income tax on residents and on people who work in the city.
